Application filed August 25, 1919. Serial No. 319,546.

To all 'whom t may concern.'

Be it known that I,.HILLIARY B. MGREE, a citizen of the United States, residing at Palmetto, in the county of Manatee and State of Florida, have invented' new and useful Improvementsin Gas and-Oil Vending Devices, of which the following isa specification.` y 1 This invention relates to improvements in liquid vending machines more particularly adapted for vuse in delivering gasolene and lubricating oils Vand-thefprincipal object of theinvention is to provide means controlled by a coin for delivering-a certain amount of liquid after which the deviceis locked and no. more liquid can be secured unless another coin is deposited.

The purpose of the invention is to provide means whereby a customer may secure a supply of gasolene or oil at a service station by depositing the correct sum for the amount of gasolene desired=so that the service of anattendant is not required. In this way the station may be opened day and night for it is impossible to withdrawany of Lthe liquid without depositing the correct sum.

Another obj ect of the invention is to provide a plurality of setsof devices whereby different rquantities of 'liquid maybe withdrawn from the tank by depositing coins of different denominations. V

vThe invention: also consists in certain other features of construction and inithe combinationand arrangement of the sev eral parts, to be hereinafter fullydescribed, illustrated in the accompanying drawings and specifically pointed out in the appended claims.;

In describing my invention-in detail, reference will be had to the accompanying drawings wherein like characters denote like .or corresponding parts throughout the sev` eral views, and in which Y l Figure lis afsectional view of theinvention. Fig. 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a perspective' View' of the case. Fig. 4 is an enlarged detail view ofthe 'lower end of the coin chute and its associatedv parts. Y

gasolene or other fluid to be vended.

Thepiston 3 ofthe pump' has its rod 4 1 provided with a rack 5 which is engaged by a ygear 6 located on the shaft,v 7, the journals of which are carried by one wall ofthe case 1' and bythe bracket- 8 secured to said case. vThe outer end of the said shaft is provided with a crank handle 9 by which the shaft maybe manually` rotated to actu# ate the pump. The inner end of said shaft carries a beveled gear 10 which is loosely mounted thereon and is'connected with the shaft by ratchet mechanism located' in the case 11. This gear 10 meshes with alike gear 12 carried by an upright shaft 13'10- cated in they case. rThis upright shaft is provided with'atootlied wheel v14 andrwith a worm 15. The toothed wheel 14 is adapted to be engaged by a tooth 16 located on'the locking `bar 17, horizontally slidableon ,the

guides 18 carried `by the inner walls ofthe case. Springs 18' hold the bar with its teeth engaging the wheel. The worm,15 is engaged by a worm wheel 19 located on a horizontal shaft 20 mounted in the case andthis'shaft 20 is provided with anumber of toothed wheels 21. A second horizontal shaft 22 is journaled in the case and this shaft 'carries a number of toothed wheels 23 which are splined to the shaft so-thatthey will rotate therewith but haveV sliding movement thereon. These Vwheels 23 are adapted to be moved longitudinally onl the shaft by tlie cams-241 and said shaft 22 is normally held Vin a certain position by thefspring 25. 'Each cam is operatedgby a lever26 which is piv'- oted at 27 and which is -operated by `a coin yas hereinafterdescribed..` The lower end of this lever is provided with an angle part 28 which is connected byapin and slot connection with an arm 29 extendingfrom one part of the cam. In this wayfwhen the lever is rocked the arm 29 will be forced forwardly 'to bring the enlargedparts of the two parts vof the cam together and thus slide the wheel 23 upon the shaft 22 and thus Vplace said wheel into mesh with; one of the release the lever 26 to permit saidlever and i with `a right-angle extension which extends i the cam part to return to normal position,

when spring 33 will returnwheel- 23 to normal position and outuof mesh with `wheel 21. Spring 25 will then rotate `shaft-22back to its normal position. I may locate a plurality of holes in each wheel 23 so the pin 32 may be adjusted. p p y The upper end of lever 26 is provided through a slot formed in the lower end of coin chute 34. A second lever 35 coperates with the upper end `of lever `26 to engage thecoin Vand `thisflever 35 is engaged by the spring 36 which tends to hold both lever 35 and lever 26 imposition" to form a rest for the coin and with the cam part in inoperative position. AThese levers also have a i pin and slot connectionwith a slide har 37,

the front end of which passes through an opening in. the locking bar17 where it is provided with a head 37 so that in its forward movement the sliding bar will pass,

through the opening without moving the locking bar, butli'nits rearward movement engages the har and causesit to move rearwardly with `it 4and thus moves the tooth l 16 out of engagement with the wheel 14.

The coin is forced between :the levers 26 and` to rock said levers bythe arms 38 which have their upper ends provided with inwardly'projecting portions engaging with l the slots 39 formed in the chute. The lower endsof these arms are connected to a crank armf 40 by a link 41 andsaid arms 38 pass through guides 42. Said arms are of curved formation so that when they are brought downwardly by rotation `of shaft 43 which carries -arrn 40 the guideswill `cause them 26 and 35.

to approach each other and thus throw their upper ends into the chute and against the coin resting upon the upper ends of levers said levers byjsaid arms it `will force the levers vapart,thuscausing lever 26 to actuate the cam part to move the wheel 23 into engagement with` the wheel 21 and lever 35` will cause the rod 37 to move the locking bar toV withdraw the tooth 16 froml the wheel 14.A This will permit the shaft 7 to bel rotated by its:` crank handle to cause the pump to be rotatediuntilit causes thewheel 23 to make a complete revolution when the pin 32 on said wheel 23 will strike the latch bar` and release the lever 26 so that the parts `are `returned to normal position and the `shaft 7 locked against further movement by Vthe tooth 16 on the locking bar 17 engaging the wheel 14 or shaft 13.

, After the coin passes the levers 26 and 35 itwill droplinto a suitable receptacle or it may fall directly on tothe floor of the case. Theshaft 43 has one end extending through the case/where it is provided with a crank handle 43.

As the coin isgforced between pump up the liquid. The shaft 7 may Y It will of course be understood that any desired number `of coin chutes and their associated parts may be used according to tho size of the'station and the device `may be madeto deliver any desired amount of liquid in one operation of the pump. Y

It is thought fromthe foregoing descrip-Y tion that the advantages and novel features of my invention will be readily apparent. .mI desire it to be understood that I may make; changes in the construction and in 1 the combination arid` arrangement of the several parts, provided that such changes fall within the scope of the appendedclaims.
